I have delta and recently upgraded to a 32bit board (SKR 1.3) and also to TMC2130 (and I have 256 micro-stepping). No matter what, when I run my usual printer calibration routine (G33 P1, P2, P5, P10) it always randomly fails. It usually fails when probing near the towers. I have no idea what to do with it because it is sometimes able to finish (eg. the P2 command). And when I run it for the secoby Kubas_inko - Firmware - Marlin
QuoteDust ok... compile and upload this 20x4 LCD test sketch. DO NOT MODIFY IT, it works as is on a RAMPS //Standard RRD smart controller LCD pins when on a RAMPS 1.4 //lcd pins #define LCD_PINS_RS 16 // #define LCD_PINS_ENABLE 17 // #define LCD_PINS_D4 23 // #define LCD_PINS_D5 25 // #define LCD_PINS_D6 27 // #define LCD_PINS_D7 29 // #define screenX 20 #define screenby Kubas_inko - RAMPS Electronics
QuoteDust Under the d in "rrd" along the top of your LCD adapter is a blob of solder that should not be. But that is on the kill button. The pins that are required for LCD are #define LCD_PINS_RS 16 #define LCD_PINS_ENABLE 17 #define LCD_PINS_D4 23 #define LCD_PINS_D5 25 #define LCD_PINS_D6 27 #define LCD_PINS_D7 29 Looking closely at the top of the LCD adapter at these 6 pins a few look dodby Kubas_inko - RAMPS Electronics

Hey everyone. So, I decided to build a second delta (because I somehow had enough extra parts just for one ). So I build it, connected everything, but there is a problem. The LCD won't work. I am using Ramps 1.4 (and it is the selected board in marlin) and normal 2004 RepRapDiscount Smart Controller. I have enabled it in marlin: // RepRapDiscount Smart Controller. // // // Note: Usually sold wby Kubas_inko - RAMPS Electronics
Hey everyone. So, I finally decided to install my brand new TMC2130 drivers. Everything went well, they are recognized with M122. Settings in marlin are mostly default, just enabled the TMC2130 drivers. But I have a big problem with them. Instead of being quiet, they are extremely loud (louder than my default A4988s). Here is a video with TMC2130 and here with A4988. Any ideas why is this happenby Kubas_inko - Stepper Motors, Servo Motors, DC Motors
QuotePippy 24V for the motors is MUCH better. But you might want to use hybrid threshold for the TMC2130's to work in both modes (speed dependent), but that will need you to discover usable threshold values for switching between stealthchop and spreadcycle. Doesn't a delta need a 32-bit board for the stepping and kinematic calculations etc to keep up ? I know that 24v is better, but that does nby Kubas_inko - Firmware - Marlin
QuoteDust What is your vmot voltage? (12v or 24v) what brand of TMC2130 , perhaps your R_SENSE value is not correct so your over driving them... 12V PSU. They are FYSETC. R_SENSE is default, thus 0.11. I don't know how should I change this.by Kubas_inko - Firmware - Marlin

Nice. now it is working. but another problem occurred. When I am moving above bed, it is higher in the middle than on the sides. And it is not problem with the bed, but the arms are pushing it up and down (which they should not when moving on x/y)by Kubas_inko - Delta Machines
Hey there. I have few question and problems, I would love to ask you guys. 1. If you look at my config, is it correct for Delta printer? 2. I have mechanical endstop switches for x,y,z min. Everyone is connected to ground and S pin on Ramps. They are set up so that they are constantly open. But my printer just won't register them. I can press them how many times I want, but they just dont work. iby Kubas_inko - Delta Machines
Quotedc42 That PSU should be OK for a Mini Kossel or for any printer without a heated bed. However, the maximum 12V current rating is only 19A, which may be too low for anything larger with a bed heater. If you are building a larger Kossel with a low-voltage bed heater, or a Kossel with 0.9deg motors, then you should use 24V power instead of 12V anyway. But it should be powerful enough right (eveby Kubas_inko - Next Wave Electronics Working Group
So, for like a year, I was storing parts for my 3ds printer. I found this old ATX PSU (attachment) from grandpas old PC and I would like to ask you, if the PSU is powerful enough to run basic delta 3d printer (Something like kossel) and if the CPU power cables (attachment) can deliver what it needs or do I need to wire it differently. Thank you very much for any response.by Kubas_inko - Next Wave Electronics Working Group
